Traffic Management

We’re building an Advanced Transportation Management System (ATMS) to help make it easier for residents to get around as Mississauga grows. The ATMS Project is a multi-year plan to invest in technology and infrastructure that will allow us to proactively monitor and respond to traffic conditions.

The ATMS Project includes:

The design of a traffic management centre to manage traffic signal operations.

Upgrade of the traffic signal communications using the City’s fibre, cellular and Wi-Fi networks.

Replacement of the old Central Traffic Computer and the traffic controller units at intersections so that signals can be managed in real time.
